If during washing you noticed the code 5D, SUD, SD, it means that the foam level in the washing machine has been exceeded. You can see it in the drum or outside the machine - on the powder tray.
What the 5D error says
Samsung models are equipped with a foam control function. If it becomes a lot, the machine goes into a mode that contributes to the suppression of foam. The resulting 5D error indicates the inability to reduce the volume of the foam - the washer waits for the foam to settle naturally. Such foam deposition usually lasts a long time, and depends on the concentration of the powder diluted in water.
All three codes - 5D, SUD, SD - indicate the same fault. The designation depends on the machine model.
Why an error occurs
If a SUD error is displayed, you first need to find out the cause of the problem. This code occurs if:
- For washing, powder was used that is not suitable for automatic machines;
- An overly concentrated powder was used, the foam of which the automatic machine could not cope with;
- Poor quality powder was used;
- The detergent dose was exceeded for one wash cycle;
- The foaming sensor has become unusable;
- The water level sensor has broken;
- Clogged hose for draining water, pipe, drain;
- A serious malfunction occurred in the operation of the control unit (but the washer shows a 5D error for this reason very rarely).
First of all, check the washing powder - often its replacement is enough to solve the problem.
What to do to fix the problem with your own hands
If the Samsung washing machine gives a 5D code when washing, and the volume of foam in the drum is large, then you need to take the following actions:
- Wait for a little deposition of foam. Washing after that will automatically resume itself. Some Samsung washing machines require you to press the start button;
- At the end of the wash cycle, clean the drain filter;
- Remove the remaining powder, for which it is necessary to run the washing machine without laundry, choosing a long washing mode and high temperature;
- Change the powder to another with the constant appearance of a large volume of foam in the drum.
But what to do when there is no foam in the drum when the code is displayed:
- Turn off the machine;
- Get out the laundry. With the door locked, drain the water through the emergency drain;
- Clean the drain filter;
- Run the machine to check the result by selecting the previous mode.
Thoroughly clean the drain and drum of powder residue.
When to call a wizard
A professional will be required to solve the problem if:
- The SD error on the scoreboard did not disappear, while there is no foam in the drum. The cause may be a foam sensor malfunction. It is necessary to replace the sensor.
- Error 5D is on after starting the Samsung washing machine or during the washing process, which stops after a pop-up code. The reason is a breakdown in the water level sensor. It must be replaced.
- The washing machine drains water without powder for a long time, and gives an error with the powder. The reason is garbage clogged in the drain pipe or sewer. To remove the error, you need to clean them.
- When starting the washer, washing or rinsing, the 5D error lights up. Sometimes it indicates a malfunction of the control unit. Most often, a block replacement is needed.
Errors are sometimes reset from the Samsung SM display by simply pressing the “Start” button after the foam has defended from the detergent.
If all the proposed measures did not help correct the operation of the washing machine, contact the repair technician.
